Multiparallel point striping pencil



March 3, 1936. G. w. HACKNEY MULTIPARALLEL POINT STRIPING PENCIL FiledSept. l2, 1954 A, NVENTOR.

Patented Mar. 3, 1936 UNITED STATES PATENT OFFICE 2 Claims.

My present invention pertains to pencils and it contemplates theprovision of a simple and inexpensive device comprising multi-leads ofvarious colors whereby with one stroke of the pencil a number ofvari-colored impressions may be made on a sheet of paper or the like.

The invention further contemplates a multicolored lead pencil that isprimarily adapted for placing the well known striped border on anenvelope to indicate air mail service.

Other objects and characteristic advantages of the invention will befully understood from the following description and claims when the sameare read in connection with the drawing accompanying this specification,in which Figure 1 is a side elevation illustrating my novel device andthe preferred embodiment, of holding the multi-colored lead thereof.

Figure 2 is a longitudinal sectional view taken in the plane indicatedby the line 2 2 of Figure 3.

Figure 3 is an edge elevation of the device.

Figure 4 is a front elevation of the lead clamping element.

Figure 5 is a side elevation of Figure 4.

Figure 6 is a transverse section taken on the line 6 6 of Figure 2.

Figures 7 and 8 are views similar to Figure 6 taken on the lines 1 1 and8 3 respectively of Figure 2.

Figure 9 is a modified form of construction in which the lead isarranged in a pencil after the manner of the well known wooden pencil.

Figure 10 is a sectional View taken in the plane indicated by the linelll-Ill of Figure 9.

Similar numerals of reference designate corresponding parts in all theviews of the drawing of Figures 1 to 8 inclusive, and particularlyreference will now be made to said figures.

The invention pertains primarily to a pencil having multi-leads of asimilar color or various colors as is desirable, and, for the purpose ofillustration only, I show the manner in the preferred embodiment as wellas in the modified form as to how these leads are held.

The casing I is preferably rectangular and of metal or the like andhollow throughout. Arranged within the hollow casing l is a leadclamping member designated as a whole by 2 having the legs 3 that arewedge shaped on their outer walls and at their lower ends. The clampingmember 2 is also provided on its lower ends with wedge shaped portions 5that coact with the wedge shaped portions 4 of the casing member.

At its upper end the clamping member 2 is rigidly secured to a threadedstud 6 that engages the threads 8 of a thumb nut l.

(Cl. 1Z0-14) Interposed between a series of multi-colored leads Iii, Iland i2 are spacers 9 and these leads are preferably flat.

In the practical operation of the device, the preferred embodiment whichwe are now considering, the operator uses the device after the manner ofa pencil and by doing so various co-lored lines may be drawn. As thetightening of the nut l pulls the lead clamping member 2 into the casingl causing the lower points of the clamp to press upon the leadspreventing their movement, so when it is desired to lengthen the leadsit is done by first loosening the clamping nut which allows the innermember to slide out of the casing, when the leads are pulled out to thedesired length by hand and then clamped into place by tightening the nutwhich reverses the operation and pulls the leads back part way into thecasing, at the same time forcing the points of the clamping membertogether, which holds the leads rmly.

What I claim is:

1. A multi colored marking pencil comprising a tubular outer casing,wedge-shaped portions formed interiorly on the lower end of the casing,lead clamping means comprising a flanged member adapted to be interposedwithinthe outer tubular casing; said inner clamping member beingwedge-shaped on its lower outer face whereby the hanged member will becontracted when the wedge-shaped portion thereof contacts thewedge-shaped portion of the outer casing, a screw having a head andadapted to be secured on the upper end of the inner casing, a thumb-nutadapted to engage the thread of the screw to move the inner memberupwardly with respect to the outer casing, multi-colored leads engagedby the inner member and spacers arranged between the leads.

2. As an article of manufacture, the combination of a outer tubularcasing having a wedgeshaped inner flange at its lower end, a clamp-ingmember within and adapted to be moved upwardly with respect to the rstcasing and being slightly beveled on its outer face at the lower endthereof whereby the inner clamping member will be contracted at itslower end when the Wedge-shaped portions of the outer casing grip thebeveled end of the inner member, means for moving the inner memberupwardly in the outer casing, leads of varied colors adapted to beclamped within the inner member and spacers adapted to be interposedbetween the various leads substantially as and for the purpose specined.

GEORGE WESLEY HACKNEY.
